Some of these are super tiny...20 beds doesn't really seem like a hospital to me. Not saying this is a good trend but I'm not sure how you stay afloat with such a small footprint.
Mount Graham Regional Medical Center in Safford, AZ, is a Level IV trauma center. It has 25 staffed beds. Safford has a population of just over 10,000, and is approximately two hours to Tuscon by car. A Level IV trauma center provides initial evaluation, stabilization, diagnosis, and, perhaps, surgery and critical care, but what it mostly provides for serious cases is transportation to a bigger hospital, especially in the case of Mount Graham, which is listed as a short term acute care facility.
This comes directly from combat medicine: Small facilities save lives, especially if they're geared up to send serious cases to bigger units. Level IV trauma centers are at the bottom of what the American College of Surgeons recognizes as a trauma center, but they're still a vital part of the infrastructure.
No it wouldn't IMHO. It cannot have the expertise, the equipment, the clubs, the social opportunities, the field trips, the sports or 101 other things that a facility with even just 10 classes can offer.
Those are very different institutions and pretending they are the same is likely deceptive when they will produce vastly different outcomes for their users.
